SPOL OPERATIONS

  1. Deployment location
  1. Deployment period
  1. Weather events during which collection is desired
  1. Typical attended radar operation schedule
  1. Estimated number of radar observation hours
  1. Please specify the desired mode of operation
  1. In addition to the standard attended operation mode, will you request “unattended remote off-site operations during which the radar can be scanned in a pre-specified scanning sequence or remotely controlled by a PI via internet? YES/NO
  1. Will you conduct Intensive Observing Periods (IOPs)? YES/NO
  2. If yes, under which circumstances?
  3. How long does each IOP last?
  1. Do you require the Ka-band wavelength radar?
  1. Please specify your communication needs (e.g., chat; internet bandwidth)
  1. How many of your staff will be available to help with S-Pol operations?
  1. What auxiliary equipment will be located at the radar site?
  2. If any, what are the size dimensions?
  3. Will equipment need to use S-Pol power exceeding 25 Amps?
  4. If so, will it require single or 3-phase power?
  5. 120 or 220 Volts?
  1. The standard S-Pol configuration has 3 scientific display stations and 3 additional seats with desk space. Is this sufficient to accommodate the maximum number of scientists and staff expected at S-Pol at any one time? YES/NO
  2. If no what additional space needs do you have?
  1. What office equipment (e.g., computers, printers, monitors) are you planning to bring to S-Pol?

TYPICAL RADAR PARAMETERS

  1. Please indicate if the following standard operating parameters are acceptable? If not please specify the requirement:

Max Range = 150 km
Unambiguous Velocity = 25 m s-1
Range Resolution = 150 m (150 to 675 m)
Type of Scans: Range Height Indicator (RHI), Plan Position Indicator (PPI), Vertically pointing, Staring
Scan Rate: RHI = 6 deg s-1 (1 to 6 deg s-1)
PPI = 10 deg s-1 (1 to 12 deg s-1)
Polarization transmitting mode:
Alternating Transmit (standard)
Simultaneous Transmit (available)
Standard S-band minimum sensitivity at various ranges:
-45 dBZ at 1 km
